Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.

Why the motion of gas molecules is also called thermal motion?

The motion of gas molecules is called thermal motion because it is directly related to the temperature of the gas. As the temperature increases, the gas molecules move faster and collide more frequently, leading to an increase in thermal energy and the overall temperature of the gas.


When the molecules in a body move with increased speed is it possible that the body will change from a gas to liquid or gas to a solid or liquid to a solid or liquid to a gas?

Molecules in a solid are tightly packed together and therefore have very low average kinetic energy. However, if you add energy to the system you are increasing the random motion of molecules and the intermolecular distance within the molecules increases thereby changing the substance into a liquid state. Same is true when going from liquid to gaseous state of matter. So only the liquid to gas phase change could occur, if all other conditions remain the same.


What is related to the motion of atoms or molecules in a substance?

The motion of atoms or molecules in a substance is related to its temperature, with higher temperatures leading to increased motion. This motion affects the state of matter (solid, liquid, gas) that the substance is in, as well as its properties such as density and viscosity. In gases, the motion of atoms or molecules creates pressure.


What is the energy of a gas?

The energy of a gas can be described in terms of its internal energy, which includes both kinetic energy due to the motion of the gas molecules and potential energy due to intermolecular forces. This energy can change when the gas undergoes processes such as heating, cooling, or expansion/compression.


How does energy from the sun affect the motion of molecules in a solid compared to molecules in a gas?

The energy from the sun increases the motion of molecules in both solids and gases by providing heat. In solids, this energy increases the vibration and rotation of molecules within a fixed position. In gases, the energy causes the molecules to move more freely and rapidly throughout the space.

What do you know about gases molecules?

Molecules of a gas are in permanent motion.


Are the molecules in a gas in constant motion?

Yes, the molecules of a gas are constantly in a random motion if the gas temperature is more than 0 degree kelvin. This random motion determines the average kinetic energy of the molecules which is equal to the temperature of the gas. I hope this answers your question.


Does gas molecules are constantly in motion?

Yes they do!


Compare the motion and spacing ofbthe molecules in a solid to the motion and spacing of molecules in a gas?

The motion of molecules in a solid will be extremely slow. The spacing is very close to one another.THe opposite is true of gas. The molecules are extremely fast and they are spaced far apart.


How does the molecular motion of a substance change as it transitions from liquid to gas?

As a substance transitions from liquid to gas, the molecular motion increases. In the liquid state, molecules move more freely but are still close together. When the substance becomes a gas, the molecules move even more rapidly and are much farther apart.


How does the motion of the molecules change during melting?

The motion of molecules is accelerated.


What is the behaviour of gas molecules based on the kinetic theory?

Gas molecules are in continuous random motion and they collide with each other.

Are molecules of a substance in motion only as a gas?

No, they are in motion in a liquid as well. In a solid they vibrate in place.
